The principle of the spirals is similar to the work of other contraceptives – they do not allow the embryo to attach to the wall of the uterus and actively develop in it. In addition, the spiral damages the sperm, which makes it unsuitable for conception. This is due to the content in the composition of the device metals. Among other things, IUDs can change the composition of the cervical fluid, which slows down the process of sperm movement.
Most intrauterine devices are designed for 5 years, but there are models whose service life ranges from 10 to 15 years. In this case, the state of health of the woman and the correct location of the device inside the uterus makes the situation. For example, if the helix has moved, it will have to be removed earlier, since in this case there may be no contraceptive effect.
IUD differ in shape, size, principles of action and the materials from which they are made. They can be round, spiral and T-shaped. The most popular is the product with attached nylon thread, the ends of which are located in the vagina so that the doctor can easily remove the spiral.
